26. e2d3 Another great move, preparing Bc2-a4. The computer also suggests stuff like the surprising g2-g4, but why complicate the game when you have total control $2 26... d7f7  27. d3c2  27... g8h7  28. e3f2 A difficult move. Aronian is in no hurry, and although I don't understand exactly what the benefits of this move are (maybe preventing h5-h4 $2), Black doesn't have much to do anyway.
